Problem 5.54 - Thermal Deformation

Problem Statement

A square brass bar is placed between two fixed walls and heated from 5 °C to 35 °C. If L = 450 mm, h = 15 mm, E = 100 GPa, and α = 20 x 10-6 /°C, determine the stress in the bar.

A long square brass bar is placed between two fixed walls. The bar has length L. The cross section is square with sides h.
